They all have different family situations. After round 1 when it looked like they were there indefinitley Hiku and Herbert went home as they had new borns and needed to be with their partners. At that point the side went over there expecting it to be the weekend it ended up looking like it was indefinite.Fusitua went back for the birth of his child and he has been absolutely dragged through the mud for it. I will tell you one thing, I would never have missed the birth of my daughter. Not for my job, not for footy, not for nothing. You may only get one chance at cutting that cord in your life - you might not even get that. To be fair I would probably have thought worse of him if he didn't go back for such a big event in his life and to support his wife.
On the resumption the understanding was the NRL would do what they could to get their families over there. These guys probably discussed it with their families and decided if they could all make it over there the father should go initially and they will meet them. It would of been hard for the partners to travel with a new born even if it is a private flight.
To me we don't know the guys family situations or how much of a support network the partners left behind have. Not our business to know.
There are too many vairables with all of this. Next year they will probably fine to travel and it might be harder for other guys.
Happy to debate their playing strengths and weaknesses and I don't hold anything against them returning home.
